Question
In a compound microscope Select one: A. magnification is provided by the objective and not by the eyepiece. The eyepiece merely increases the brightness of the image viewed B. the total magnification is is m,* M2, where m, is the lateral magnification of the objective and M2 is the angular magnification of the eyepiece O C. The total magnification is m1 + M2 where ml is the lateral magnification of the objective and M2 is the angular magnification of the eyepiece. D. both the objective and the eyepiece form real images. E. magnification is provided by the objective lens and not by the eyepiece. The eyepiece merely increases the resolution of the image viewed.Explanation / Answer
IN a compound microscope
1. total magnification is m = mo * me or Vo/u(1 + D/fe) ( near point)
2. final image is formed at m = -LD/fofe
3. the image formed through objectiv is real magnififed and inverted image.
4. this image acts as object for eyepeice
5. this image is made to form below the focus of the eye piece Fe.
6. thus final image is virtual magnified and inverted at the near point.
7. magnifying power is defined as the ratio between the angle subtended by the image at the
near point at the eye piece and the angle subtended by the object at the eyepeice
